How to Choose Geomembrane
Hdpe geomembrane has many functions such as impermeability, isolation, protection and reinforcement.
Hdpe geomembrane is a kind of waterproof barrier material with high polymer as the basic raw material, mainly divided into low density polyethylene (LDPE), high density polyethylene (HDPE) and EVA geomembrane. Specific functions are as follows:
Anti-seepage effect:
polyethylene geomembrane has a very low permeability coefficient, can effectively prevent liquid leakage, so it is widely used in landfill, sewage or waste residue treatment plant, reservoir, drinking water tank, storage pond and other need to prevent harmful substances from infiltrating into the underground water source projects.
Isolation:
Geomembrane can separate soil, sand and other materials with different properties, prevent mixing, and maintain the original characteristics and functions of each layer of materials.
Protection:
In some areas vulnerable to water erosion or wind erosion, such as riverbanks, roadbeds, etc., geomembrane can protect the soil from erosion, but also protect other geotechnical structures from damage.
Reinforcement:
Through the combination of geomembrane and other geomaterials such as geogrilles, the stability and bearing capacity of the soil can be enhanced, and the overall performance of the project can be improved.
Polyethylene geomembrane detection content includes
Appearance quality inspection:
Check the appearance of the geomembrane, observe whether there is damage, cracks, holes and other phenomena.
Size detection:
Including the measurement of thickness, width, etc. to ensure that the size of geomembrane meets the design requirements.
Physical properties test:
The purpose of the test project is to evaluate the strength and durability of the geomembrane, including tensile strength, elongation at break, tear strength, expansion properties, etc.
Impermeability test:
By testing the impermeability of the geomembrane, its effect in preventing liquid penetration and soil erosion can be determined. Test methods include water permeability test, permeability test and so on.
Chemical performance test:
Evaluate the stability and corrosion resistance of geomembrane in different chemical environments, including corrosion resistance and chemical resistance.
Environmental adaptability test:
Simulate the use environment of geomembrane to evaluate its stability and durability under different environmental conditions, including aging resistance and ultraviolet resistance.
Welding quality inspection:
For the geomembrane that needs to be welded, the quality of the welding site is tested to ensure welding strength and tightness.
